SELECTED ONGOING PROJECTS
- Distinguishing cancer cells based on their biophysical signatures
(supported by Région HdF (comp.) and I-SITE ULNE)
Changes in cell shape and structural integrity affect many biological processes related to cells. Therefore, we can potentially use the biophysical properties of cells to reflect the state of their health. This connection between the biophysics and diseases has been attracting scientific research attention, especially for cancer research, where diseased cells proliferate uncontrollably and disrupt the organization of tissue. Here, we target a reliable and practical high-throughput technique to obtain the biophysical signature of cancer cells. We take two parallel approaches to achieve this goal. We use MEMS grippers (i.e., Silicon NanoTweezers) that provide higher sensitivity to examine different biophysical properties (e.g., size, stiffness, viscosity, and electrical properties). In parallel, we are developing a high-throughput MEMS device optimized according to the SNT results for clinical applications.
- Monitoring immunological synapses at single cell level in a microfluidic device
(supported by Fondation ARC)
We develop a microfluidic device for trapping cell-pairs to monitor cellular communication. The proposed method allows cell positioning at designated areas to make selective contact between two different populations despite dimensional variations. An array of trapping sites with specific geometries provided higher efficiency, and integrating the setup with an incubation unit allows long-term (>4 hours) experiments under a controlled environment. The device is used to monitor the cellular activity of patient immune and leukemic cells via Ca2+ signalling by fluorescence microscopy.
- Real-time measurement of the physical properties of DNA-ligand complexes
We are using a MEMS gripper device, Silicon Nanotweezers (SNT), to monitor the stiffness of λ-phage DNA through increasing concentrations of ligands (such as Doxorubicin (a DNA binding drug widely used in chemotherapy), SybrGreen and Hoechst) in real-time. The study of the mechanical properties of DNA-ligand complexes can provide valuable insight on the biological implications of such complexes in-vivo.
